3 claims. (ci. ,12a- 96) This invention relates toutru'sses,particularly for the treatment of inguinal hernia, iandhasffor itsobjects to improve on the padstructur'e; f

such trusses and also on the manner of mount-,

ing and carrying the same whereby to enhance the practical andcommercial value thereof.

The invention is fully described in the following specification, and oneembodiment thereof illustrated lin the accompanying drawing, in Which-Figure l is a front view of a truss embodying the invention; Fig. 2 is aface view of the pad member, together 'with a fragmentary portion of themember on which mounted, to a slightly enlarged scale; Fig. 3 is anenlarged section on the line 3-3 in Fig. 2, -showing the compression orface member of the pad in normal position; Fig. 4 is a similar sectionshowing said compression or face member in compressed position, and Fig,5 is a cross-section on the line 5 5 in Fig. 2. Figure 6 is an enlargedview of one of the hip engaging strips.

Referring to the drawing, I designates the pad body which issubstantially of plate-formv and round or oblong, as desired, with itsfront surface substantially flat and preferably rearwardly rounded atthe edges, as shown. The body I is faced with a yielding pad or cushionmember 2 of soft rubber, or other suitable pliant material for bearingagainst the body of the :1i-ser. This cushion pad is provided at itsinner or rear edge with an inturned flange 3 adapted to yieldinglyengage around the edge of the body plate to retain the pad thereto. Theouter marginal edge of the pad 2 is provided with a rigidor lbeadlikepart 4 extending entirely around the pad and being in contact 'with andbacked by the marginal edge portion of the body l. The portion of thepad within this edge ,bead forms a compressible cushion part 5 ofconcavo-convex form, which is spaced from the body plate I and normallyprojects outward therefromin a plane common to the outer forward surfaceof the bead 4, as shown in Figs. 3 and 5.

Upon application of the pad to the part of the body to be treated, thecushion part 5 is compressed by pressure against the body until limitedby the contact of the bead 4 with the body in surrounding relation tothe rupture, as illustrated in Fig. 4, thus causing a predeterminedpressure to be applied to the rupture. The space 6 between the cushion 2and body plate I forms an air pocket which tends to cushion the actionof the cushion part 5. The cushion pad 2 may be easily removed from thebody plate and replaced by a'new one when'desired.

l y The mounting for the pad body r`I comprises a U'shap 'ed Vorbail-likel member Iof spring band ymetal stock, with its' legs shortYand pivoted to diametrically spaced ears II on the body plate I near itsedges by screws I2. The cross loop of the member I 0 is substantiallyparallel and disposed in slightly spaced relation to the Iplate I topermit rocking movements of one relative to the other on the pivots I2and also to permit yielding inward springing movements of said crossloop portion toward the plate. k

A bar I3 is clamped crosswise to the bail member I 0 centrally of itsends by'a bolt I4 which projects through registering apertures in thetwo and has the nut I5 applied to its inner end between the body plateand bail member in spaced relation to the former. The head end of thebolt I4 is countersunk in the bar. The loop portion of the member I llseats in a notch I6 (Fig. 5)in the bar I3 to permit limited pivotaladjustment of the bar on the member about the bolt I4, as an axis.

The outer side of the bar I3 is longitudinally grooved to provide a seatfor a stiff carrying wire I8 which is clamped thereto by eye-bolts I 9through the eye of which it extends. In'the present instance, the wire IB also seats in a cross groove in the head of the bolt I4, as shown, tohold it from turning in the bar I3. One or two pads may be adjustablymounted on the wire I5 for the treatment of a single or double hernia,r

as desired. l

The wire I8 at each end laps and is attached to a respective hipengaging band strip 20 formed from at sheet metal stock. This strip isof ogee curve form edgewise thereof to Aadapt it to pass rearwardlybelow the abdomen, and then upwardly and rearwardly over the hip, andthen rearwardly in curved conformance to the body Ilatwise of the strip.The outer end portions of the wire I8 and the strips 20 are encased inleather, or other suitable material, 2 I, which may continue beyond therear ends of the strips to formconnecting straps around the body, suchconnection being eiiected in any suitable manner, as well understood inthe art.

It is apparent that I have provided a truss pad which is attached to thecarrying band for yielding inward and outward movements dueto theyieldability of the spring bail member I0 and also for differentialrocking movements both with respect to the axis of the band pivots I2and the axis of the bolt* I4, thus adapting the pad to lfreelyaccomodate itself to the part to which applied and to movements of thebody. It is alsoA apparent that the cushion facing member 2 of the padcontributes to ease of Wearing and eiciency in use.

I Wish it understood that my invention is not limited to any specicconstruction, arrangement or form of the parts, as it is capable ofnumerous modifications and changes Without departing from the spirit ofthe,` claims.

Having thus described my invention, what I claim as new, and desire tosecure by United States Letters Patent, is:

1. A truss of the class described comprisinga, pad body having a pair ofspaced rearwardly projecting ears, a U-shaped bail of springmaterialextending across the pad body with its legs short and pivoted to saidears for rocking movements relative to the pad member, a carryingmember, and means connecting said carrying member to said bail forlimited rocking movements relative to the bail about a pvot transverseto the bail pivot.

2. A truss ofthe class described havingy a pad body with spaced earsprojecting therefrom, a 25 shallow U-shaped bail of spring materialextending crosswise of said body and having its'legs pivoted to saidears for rocking movements relative to said body, a cross bar pivotailymounted on the loop portion of said bail for limited rocking movementstransverse to. the rocking movements of the bail, and means carried bythe bar for clamping engagement with a carrying member.

3. In a truss` of the class described. a band having a wire portion, apad body mounted on said wire portion for adjustment lengthwise thereof,said mounting comprising a bail member .of spring material disposedcrosswise of the pad body and having its legs pivoted to the pad body tohave rocking movements transverse thereto, the loop portion of said bailbeing spaced from the pad and yieldable inward and outward relativethereto, a cross bar mounted on said bail for limited' rocking movementson an axis transverse to the bail axis, the outer side of said barhaving a longitudinally extending recess for receiving vsaid wiremember,and eye-bolts on the bar receiving and clamping the wire member thereto.CHARLES RAW.
